As far as pointless apps, the zippo lighter application is already available, and I'd like to see the xray and beer applications available too. There are a lot of stupid apps on the iPhone that I'd like to have access to just because.
I really hope someone creates a REAL flashlight app that utilizes the dual LED flash instead of keeping the screen on. Otherwise, why bother?
On my blackberry, you can change the settings in camcorder mode to have the flash always on. That way you just set a shortcut to camcorder and you have instant blinding light. I'm sure this will be an option on the Droid as well. Or at least I hope so!
Yeah, that's an old trick that I used years ago with my Nokia N75 and N95, but I've had phones sinces that wouldn't allow flash to run in video mode, so that's why I hope it's a non-issue.
